Description

  The present invention relates to a spray device for spraying a liquid such as an emulsion or a perfume.

  A conventional spray device 100 disclosed in FIG. 1 is provided with a sleeve 102 below a spray head 101 including a nozzle 101a, and a suction tube 103 that extends through the sleeve 102 to the outside. A conical tube 104 is fitted to one end of the suction tube 103. A base tube 105 is inserted into one end of the conical tube 104. Holes 105a are formed in opposing positions on the outer peripheral surface of the base tube 105, respectively. The hole 105a is formed at a position covered by the conical tube 104 when the base tube 105 is inserted. An elastic body 106 is provided at one end of the base tube 105, and a sphere 107 is provided at one end of the elastic body 106.

  A storage tube 108 is provided separately. The suction tube 103, the cone-shaped tube 104, the base tube 105, the elastic body 105, and the sphere 107 are stored in this order in the storage tube 108 from one end. Further, a suction pipe 109 is provided at one end of the storage pipe 107.

  According to the structure described above, when the spray device 100 is used, when the spray head 101 is pressed, the air in the container is instantaneously directed toward the play head 101 and ejected from the nozzle 101a. At the same time, the emulsion or perfume in the spray device enters the storage tube 108 from the suction tube 109 together with air by the siphon effect. In this case, the sphere 107 is pressed against one end of the base tube 105 by the elastic force of the elastic body 106, and the sphere 107 closes the hole in the storage tube 108.

  In the above-described state, a gap is further generated between the base tube 105 and the cone-shaped tube 104, and the emulsion or perfume in the storage tube 108 is formed in the outer peripheral surface of the base tube 105 along the gap. The liquid 105 or the perfume is ejected from the nozzle 101 a of the spray head 108 through the suction pipe 103 through the suction pipe 103.

  When the pressure of the spray head 101 is released, the emulsion or perfume in the storage tube 108 flows in the reverse direction and returns to the container.

  The structure of the conventional spray device 100 described above is effective in spraying emulsion or perfume. However, in the case of injection molding with a plastic material or the like, the living material passes through 105a formed on the outer peripheral surface of the base tube 105. When this occurs, burrs are easily generated. Such drawbacks affect the difficulty of the assembly process during manufacturing, leading to a decrease in yield.

  Further, since the sphere 107 is made of a metal material, it lacks elasticity. Therefore, the operation of the spherical body 107 reacting sensitively to block the hole of the storage tube 108 cannot be performed. Conventional spray device constructions need to remedy these drawbacks.

  This invention makes it a subject to provide the spray apparatus which can suppress generation | occurrence | production of the burr | flash at the time of injection molding in a production process, and can suppress the fall of a yield.

  Another object of the present invention is to provide a spray device that reacts sensitively under pressure and achieves an operation of closing the hole.

  Therefore, as a result of intensive research in view of the drawbacks found in the conventional spray device, the present inventor has provided a nozzle with a nozzle and an output tube inside, and a hollow tube. A pressing pressure bar with one end formed as a flange to be abutted and a hollow tube at the other end, an elastic body inserted into the hollow pipe part of the pressing pressure bar, and a through hole are formed to form the pressing bar. With the cap part to insert the crush. A connecting rod in which a plurality of guide grooves are formed in the outer peripheral surface along the axial direction, and a columnar portion inserted into the hollow tube portion is used as one end, and a stopper protrusion edge portion is formed along the outer periphery at the other end. And an insertion hole for inserting the connecting rod, and one end is in airtight contact with the corresponding stopping edge and is reciprocated by the urging force of the elastic body, and is hollow and has an inner diameter at one end. A cylinder formed by forming a cylinder chamber to be reduced and stored, a cylinder formed with a lower end having a flow passage and a connection port therein, a spiral shape, and a passage hole formed at the upper end. A spray device comprising: a first end portion; a lower end as a second end portion; and an elastic valve provided with a closing portion for closing the flow passage between the first end portion and the second end portion.

In order to explain the structure and characteristics of such a spray device, a specific example will be given and described in detail below with reference to the drawings.

  As disclosed in FIGS. 2 and 3, the spray device 10 according to the present invention is provided with a nozzle 11 for ejecting a liquid, and includes a pressing portion 1 having an output tube 12 therein and a hollow tube body. 1 is formed with a flange 21 that is in contact with one end, and the other end includes a pressing rod 2 that has a hollow tube portion 22 through which liquid flows.

  Further, the elastic body 3 that is inserted into the hollow tube portion 22 of the pressing rod 2 to give an urging force, the cap portion 4 that forms the through hole 41 and inserts the pressing rod 2, and the outer peripheral surface in the axial direction A plurality of guide grooves 52 are formed along one end and a columnar portion 51 inserted into the hollow tube portion 22 is used as one end, and the other end of the connecting rod 5 is formed with a stop protrusion 53 along the outer periphery. With.

  In addition, an insertion hole 61 for inserting the connecting rod 5 is formed, and at one end, a piston 6 that is in airtight contact with the stopper protrusion 53 and reciprocated by the urging force of the elastic body 3 is provided.

  Further, it is hollow, the inner diameter is reduced toward one end, the inner diameter is larger than the lower end, and an upper end portion 71 that forms a cylinder chamber 711 that houses the piston 6 and the connecting rod 5, and the inner diameter is larger than the upper end. A cylinder 7 is provided which has a small flow passage 721 and a connection port 722 formed therein and a lower end portion 72 connected to the suction pipe 30 extending toward the container 20.

  Further, it has a spiral shape, a passage hole 84 is formed at the upper end to form the first end 81, the lower end to the second end 82, and the second end 82 is provided with a blocking portion 821 that blocks the flow passage 721. At the same time, it is provided between the first end portion 81 and the second end portion 82, and the closing portion 821 reciprocates with respect to the flow passage 721 so as to move upward and close, and move downward to open. An elastic valve 8 configured as described above is provided.

  The above-described pressing portion 1, pressing rod 2, elastic member 3, cap portion 4, connecting rod 5, piston 6, cylinder 7 and elastic valve 8 are assembled and a fixing member 9 is used. Connected to the container 20. The fixing member 9 is a cylindrical member in which a thread is formed, and a packing member 91 that is in close contact with the mouth of the container 20 is provided to prevent fixation and leakage of contents in the container 20.

  As shown in FIG. 4, when the pressing portion 1 is pressed downward, the pressing rod 2 and the connecting rod 5 receive the pressure and sequentially move downward, and at the same time, gradually compress the space at the lower end of the cylinder 7. As a result, the hydraulic pressure increases, and accordingly, the closing portion 82 of the elastic valve 8 closes the flow passage 721 of the cylinder 7. For this reason, the cylinder 7 is sealed.

  In the state described above, the contact edge 53 of the connecting rod 5 is separated from the piston 6, the position where the guide groove 52 of the connecting rod 5 is formed is the outlet away from the piston 6, and the liquid becomes high pressure and instantly becomes hollow. It ejects from the nozzle 11 via the pipe part 22 and the output pipe 12.

  In the process of pressing the pressing part 1 and ejecting the liquid, since the elastic valve 8 has elasticity, it reacts sensitively and quickly moves downward to close the passage. Therefore, it is possible to achieve a quick reciprocating motion with a sensitive reaction.

  As shown in FIG. 5, when the pressure on the pressing portion 1 is released, the pressing rod 2, the connecting rod 5, and the pressing portion 1 are moved upward by the urging force of the elastic body 3. The stop edge portion 53 is in a state of being closed in an airtight manner against the piston 6. In this case, the pressure in the cylinder chamber 711 is lower than the pressure in the external environment. For this reason, the closed portion 821 that closed the flow passage 721 of the cylinder 7 is naturally separated and opened, and the position of the passage hole 84 of the elastic valve 8 enters the cylinder 711, and the pressing pressure of the next pressing pressure portion 1 is increased. It will wait.

  The spray device according to the present invention has the following features and effects. That is, instead of the conventional sphere, by providing the elastic valve 8 having an elastic function to expand and contract, the flow passage 721 can be quickly closed by reacting sensitively. That is, a sensitive, quick and stable reciprocating motion can be obtained.

  Further, by forming a plurality of guide grooves in the axial direction on the outer peripheral surface of the connecting rod 5, it is possible to suppress the generation of burrs in the production process and increase the yield.

  The above is a preferred practice of the present invention, and does not limit the scope of implementation of the present invention. Accordingly, any modifications or changes that can be made by those skilled in the art, which are made within the spirit of the present invention and have an equivalent effect on the present invention, are all included in the claims of the utility safety registration of the present invention.
